' SPECIFICATION forming part of Letters Patent No. 758,550, dated April26, 1904.

l Application filed May fi, 1903- Serial No. 155,722. (No model.)

To all whom, it may concern.- Be it known that we, WILLIAM H. MERRI'rTand JOHN C. WALL, both citizens of the United States, and residents ofGenesee, in the county of Allegany and State of New York, have inventeda' new and Improved Power-Transmitter, of which the following is a full,clear, and exact description,

The object of the invention is to provide a new and improvedpower-transmitter which is simple and durablein construction, veryeffective in operation, and arranged for transmitting thepower of amotor or the like to pumps or other machines'in such a manner as toequalize the strain and to insure a uniform and easy running of themachine.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in bothviews.

Figure 1 is a plan view of the improvement, and Fig. 2 is a sectionalside elevation of the same.

On a suitable foundation A is bolted or otherwise secured the main frameB, in which is journaled a transversely-extending shaft C, carrying apulley O and connected by belt with a motor or like driving power forimparting a rotary motion to the said shaft C. On the latter and withina chamber B, formed in the frame B, is secured a bevel gear-wheel C inmesh on opposite sides with bevel gearwheels D and D, secured on theinner ends of auxiliary shafts E and E, standing at right angles to theshaft O and likewise journaled in suitable bearings carried by the frameB.

On the outer ends of the auxiliary shafts E E are fastened bevelgear-wheels F and F in mesh on opposite sides with a master gearwheelGr, mounted to rotate on a stud B integrally formed on the top of theframe B directly over the chamber B, as plainly illustrated in thedrawings.

On the master-wheel G are bolted or otherwise secured eccentrics H andH, connected by eccentric'straps and rods with the pump or other machineto be actuated, and the said eccentrics. H and H are arrangeddiametrically opposite each other on opposite sides of the master-wheelG, so as to equalize all strain and insure an easy running of themachine,

7 especially as the transmission of the power from the main shaft C tothe auxiliary shafts E E and from the latter by the gear-wheels F F tothe master-wheel G .is likewise on opposite sides of the latter. Theeccentrics H and H are preferably made solid, as indicated in thedrawings, and upward movement of the master gear-wheel G is prevented bya cap I, secured on the top of the stud B and extending over the outerend of the hub of the Inaster gear-wheel G.

form and easy running of the machine is insured.

The device is more particularly designed for use in oil-fields forworking a plurality of pumps long distances apart. 1t frequently happensthat more wells are to be pumped on one side of the machine than on theother side. Hence if an ordinary crank-arm or wrist-pin is used on themaster-wheel instead of eccens tries the strain is unequal on themasterwheel and the latter turns by jerks. This is avoided by the use ofthe eccentrics, of which one is coupled with one half of the pumps andthe other eccentric actuates the other half of the pumps.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. Apower-transmitter comprising a frame havinga chamber formed therein, a driven shaft, extending within said chamber,a master-wheel, a stud on the'top of the frame above the chamber and onwhich the master-wheel is mounted to rotate, means for transmittingpower from the driven shaft to the master- Wheel on opposite sides ofthe latter, and eccentrics mounted on the hub of the masterwheel andsecured thereto, as set forth.

2. A power-transmitter comprising a frame having a central chamber, adriven shaft journaled in said frame, a gear-wheel carried by saidshaft, auxiliary shafts at angles to the driven shaft, two gear-wheelscarried by each of said shafts, of which the inner gear-wheel is in meshwith the driven-shaft gear-wheel, and a master gear-wheel mounted toturn above the said chamber and in mesh with the outer gear-wheels onthe auxiliary shafts, as set forth.

3. A power-transmitter comprising a driven shaft, a gear-wheel carriedby said shaft, auxiliary shafts at angles to the driven shaft, twogear-wheels carried by each of said shafts, of which the innergear-wheel is in mesh with the driven-shaft gear-wheel, a mastergearwheel in mesh with the outer gear-wheels on the auxiliary shafts,and eccentrics secured on the master-wheel, diametrically on oppositesides of the center of the master-wheel, as set forth.

4. A power-transmitter comprising a frame having a central chamber, astud extending from the top of the chamber, a driven shaft journaled inthe said frame, a gear-wheel carried by the shaft inside of the saidchamber,

bevel gear-wheels in mesh with the said drivenshaft gear-wheel, onopposite sides thereof, auxiliary shafts journaled in the said frame andextending at right angles to the drivenshaft, the said auxiliary shaftscarrying said bevel gear-wheels on their inner ends, gearwheels on theouter ends of the said auxiliary shafts, and a master gear-wheel,mounted to turn on the said stud and in mesh with the said gear-wheelson the outer ends of the said auxiliary shafts, as set forth.

5. A power-transmitter comprising a frame having a central chamber, astud extending 4 from the top of the chamber, a driven shaft journaledin the said frame, agear-whecl carried by said shaft inside of the saidchamber, bevel gear-wheels in mesh with the said drivenshaft gear-whee],on opposite sides thereof, auxiliary shafts journaled in the said frameand extending at right angles to the driven shaft, the said auxiliaryshafts carrying said bevel gear-wheels on their inner ends, gearwheelson the outer ends of the said auxiliary shafts, a master gear-wheel,mounted to turn on the said stud and in mesh with the said gear-wheelson the outer ends of the said auxiliary shafts, and solid eccentricssecured on the said master gear-wheel and arranged diametrically onopposite sides of the center of the master gear-wheel, as set forth.

6. A power-transmitter, comprising a frame having a central chamber, astud extending from the top of the frame above the chamber, a drivenshaft journaled in the frame, a gearwheel carried by said shaft withinthe said chamber, a master gear-wheel having a hub mounted to turn onthe said stud, means for driving the master gear-wheel from thegearwheel on the driven shaft, eccentrics secured to the master-wheel,and a cap secured on the top of the stud and extending over the outerend of the hub of the master gear-wheel, as set forth.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
